Detailed Product Description

This Dynamite Friction rotor is part of the DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on delivering enhanced braking efficiency through advanced rotor surface technology. The drilled and slotted design helps to evacuate gases, dust, and water from the braking surface, reducing brake fade and improving pedal feel under demanding conditions. The vented rotor construction further aids in heat dissipation, which is critical for maintaining rotor integrity and brake performance during extended use.

The rotor's nominal thickness is 34 mm, with a discard thickness of 32 mm, ensuring a long service life before replacement is necessary. The rotor features a plain disc finish combined with a Geospec silver grey hat finish that provides rust resistance, helping to maintain structural integrity and appearance over time. The five bolt holes and stud/lug hole pattern with a 127 mm bolt circle diameter ensure compatibility with specified Dodge and Jeep models.

Applications and Problem Solving

• Replaces worn or warped rotors on Dodge Durango and Jeep Grand Cherokee
• Addresses brake fade caused by overheating during heavy braking
• Improves braking performance in wet or dusty conditions with slotted and drilled surface
• Reduces rust and corrosion on rotor surfaces for longer service intervals
• Ensures proper fitment and alignment with exact bolt hole and center hole dimensions

Installation Notes and Tips

When installing the Dynamite Friction 830-42009L rotor, ensure the rotor thickness is within the specified nominal and discard limits. Proper cleaning of the rotor surface before installation is recommended to remove any protective coatings or residues. Verify the directional orientation of the rotor to match the vehicle’s rotation for optimal performance. Use appropriate torque specifications for the five lug bolts to secure the rotor firmly.
